that was my impression, Protomotive and Vivids are "suppose" to. I run the highest octane the race track has (leaded) and huge difference in power. but make sure to run several tanks of unleaded through after to save your oxygen sensors. (yes this is ok do a seach before saying something stupid!)

I have k-24 hybrids and keep the boost at 1 bar at the track and run race fuel mostly to protect from detonation and cooler cylinder temps. the car has plenty of power on the track for the Z06's and GT3's
